LoongArch: testsuite:Fix fail in gen-vect-{2,25}.c file.

1.Added  dg-do compile on LoongArch.
  When binutils does not support vector instruction sets, an error occurs
because the assembler does not recognize vector instructions.

2.Added "-mlsx" option for vectorization on LoongArch.

gcc/testsuite/ChangeLog:

	* gcc.dg/tree-ssa/gen-vect-2.c: Added detection of compilation
	behavior and "-mlsx" option on LoongArch.
	* gcc.dg/tree-ssa/gen-vect-25.c: Dito.
